Abstract: A telepresence conferencing system is disclosed in which scheduling and resource and personnel reservations may be made across various entities (i.e.; domains). Additionally, each location that is part of the telepresence conference may selectively, and independently of the other locations, designate all or selected portions of its media stream be carried over a different network from the one used to setup, control, and reserve resources for the telepresence conference.

Abstract: In a system and method for facilitating an telephony carrier to make transactions with carrier customers and/or carrier suppliers, one or more parameters are monitored and the telephony carrier is automatically to be triggered to send an offer to at least one of the carriers when at least of the parameters reaches a predetermined threshold. Preferably, the parameters are related to telephone capacity handled by the telephony carrier, and the offer is an offer to buy capacity from existing or new carrier suppliers or an offer to sell capacity to carrier customers. Thus, the efficiency of transactions is substantially increased.
